The image uses shading as a way to show movement and motion. The darker shades are either used to show things that are farther away or that is intentionally made to draw your attention. The components of the image includes:

My reflection in a window, what is behind me in the reflection, what is in front of me in the reflection and what it is that I am currently thinking about.

My reflection can be seen clearly in the center of the image. I use the shading to direct the flow of the viewer’s eyes.
